    Description: Temporomandibular disorders are characterized by ear pain, tinnitus, difficulty in chewing, dysphagia and also dizziness, cervical limitation of range of movement (ROM) and other less common disorders. Numerous recent studies associate the presence of these signs and symptoms with an elongated styloid apophysis, as in the case of Eagle syndrome. The purpose of this clinical case is to support the thesis of a common syndrome that temporomandibular joint (TMJ) disorders with an elongated styloid process affirming the relationship between temporal bone, mandibule, hyoid bone and tongue. The patient was a 57-year-old woman who reported having ear algia and tinnitus all on the right side with difficulty chewing accompanied by odynophagia and dysphagia of solid and liquid foods, as well as cervical disorders. Computed tomography (CT) scans of the neck showed elongation and ossification of the styloid processes of the temporal bone. Magnetic resonance imaging (MRI) showed an anterior right dislocation of the TMJ articular disc. The patient presented classic symptoms of temporomandibular disorders, with the primary examinations showing an anterior right dislocation of the articular disc of the TMJ, as well as a longer styloid process on the same side. We therefore suggested that, in this case report, TMJ disorders may be associated with a longer styloid process on the same side.

    Description: The craniocervical-mandibular system works in harmony and allows different functional tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affect this functional arrangement. Notwithstanding this system considered as a functional arrangement, may offer various clinical explanations, it does not hold anatomical connections with the posterior region of the cranium, thus it should not be refered to as a craniocervical arrangement. For this reason a new interpretation of such system as the tongue, mandible, hyoid system should be considered. Such functional reinterpretation between these three anatomical structures allows further comprehension of specific clinical conditions connected to deglutition aspects or the temporomandibular joint, for such needs to be taken into account during clinical diagnosis and treatment.

    Description: Summary The work in this article defines an innovative approach to evaluate the performances of gas turbine based systems. This approach allows to link the thermodynamic and mechanical model of a gas turbine with its control system while bypassing the necessity to model the electrical generator. A non‐dimensional group, called Aergia number, has been experimentally correlated with the measured electrical power output through a linear function. The Aergia number reproduces with accuracy the electrical power output during both steady state and transient operation. Furthermore, the proven linearity of the model implies that, in principle, its implementation requires the knowledge of just two data points during steady state operation. The model has been validated using two experimental facilities within the ENEA Casaccia Research Center, each equipped with a Turbec T100 S3 micro gas turbine, but characterized by different gas paths. Furthermore, the same linearity relation has been confirmed for aeroderivative and heavy duty single‐, dual‐, and triple‐shaft gas turbines with power outputs ranging from 2 to 330 MWel. In light of these findings, the non‐dimensional group Aergia positions itself, at least, as a rule of thumb for evaluating gas turbine off‐design power output and, on a broader perspective, as a valid performance indicator in the definition of a gas turbine digital twin. An innovative gas turbine modeling approach capable to estimate the engine power output by measuring easily accessible thermodynamic and mechanical quantities is presented. In principle, the knowledge of only two steady state operating points is required to characterize the gas turbine power output under almost any operating condition. The model has been validated by measuring the steady state and transient operation of two micro gas turbines. The concept has been also validated for heavy duty and aeroderivative gas turbines.

    Description: A prototype of high-temperature superconductors (HTS) Axial Flux Permanent Magnets, Synchronous Machine in a single-side configuration is presented. The stator and the rotor disc have the same outer diameter Dout of 316 mm and its air gap is set at 5 mm. HTS coils placed on the stator disc and permanent magnets placed on the rotor disc have been used to assemble the Y-connected ironless armature concentrated winding and the field winding, respectively. Each phase of the armature winding is composed by two coils connected in series, although the ac power loss is the key problem: this might be less important for wind turbine applications interested by low armature frequency. Preliminary tests at the liquid nitrogen temperature on the prototype in generator and motor mode at different load conditions have been conducted in our laboratories: the characteristic curves (power, torque, efficiency, etc.) at different rotational speed are reported. A proper response at 77 K has been provided by the prototype so that HTS coils can be used to assemble armature windings for low-frequency applications. The test results show that the HTS permanent magnet machines in the axial flux configuration are more compact, efficient, and light weight than their conventional counterpart.

    Description: Background: Twiddler’s syndrome consists of rotation or manipulation of an implantable pulse generator (IPG) in its subcutaneous pocket by a patient, thus causing hardware malfunction. Methods: This syndrome is being reported more frequently in patients treated with deep brain stimulation (DBS). Results: We report the case of a woman who had received bed nucleus of stria terminalis (BNST) electrodes for obsessive-compulsive disorder (OCD) and developed twiddler’s syndrome a few months after surgery, causing hardware malfunction due to obsessive manipulation of the IPG. Conclusion: The patient did not have compulsions related to touching objects at admission, thus making it difficult to foresee and prevent TS.

    Description: High-level young athletes need to face a wide spectrum of stressors on their journey to élite categories. The aims of the present study are (i) to evaluate session rate of perceived exertion (sRPE) at different training impulse (TRIMP) categories and the correlations between these two variables and, (ii) evaluate the correlations between sRPE, fluid loss, and carbohydrate consumption during exercise. Data on Edward's TRIMP, sRPE, body mass loss pre- and post- exercise (∆), and carbohydrate consumption (CHO/h) during exercise have been acquired from eight male junior cyclists during a competitive season. One-way ANOVA and correlation analysis with linear regression have been performed on acquired data. sRPE resulted in a significant difference in the three TRIMP categories ( 〈 0.001). sRPE resulted in being very largely positively associated with TRIMP values ( 〈 0.001; R = 0.71). ∆ as well as CHO/h was largely negatively related with sRPE in all TRIMP categories ( 〈 0.001). The results confirmed the role of fluid balance and carbohydrate consumption on the perception of fatigue and fatigue accumulation dynamics independently from the training load. Young athletes' training load monitoring and nutritional-hydration support represent important aspects in athlete's exercise-induced fatigue management.

    Description: Purpose: We report on a patient affected by Status Distonicus who was treated with Deep Brain Stimulation electrodes implanted in the Globus Pallidus internus (Gpi) and used for serial radiofrequency lesions. Materials and Methods: The evolution of radiofrequency lesions was monitored by post-operative and late Magnetic Resonance Imaging (MRI). After the first lesion the patient did improve, though not in a significant fashion. Therefore, three further radiofrequency lesions were delivered 2, 4 and 6 days respectively after surgery with subsequent improvement of dystonic movements. Results: MRI scans performed at 8 days, 3 months, and 6 months after surgery showed a diffuse T2-hyperintense and T1-hypointense GPi signal alteration which progressively decreased over time. Conclusion: We confirm that the possibility to stage pallidotomies over time using a couple of new contacts is a safe and efficacious procedure in treating SD patients where the lesions themselves are limited by the appearance of side effects, or in patients showing a poor response to a single lesion. As far as we know, this is the first description of MRI evolution and monitoring of a staged pallidotomy.
